Determine the longest visible wavelength

Reference no: EM13301622

A film of oil lies on wet pavement. The refractive index of the oil exceeds that of the water. The film has the minimum nonzero thickness such that it appears dark due to destructive interference when viewed in visible light with wavelength683 nm in vacuum. Assuming that the visible spectrum extends from 380 to750 nm, what is the longest visible wavelength (in vacuum) for which the film will appear bright due to constructive interference?
